Hello Hiroki, This is great. I've been looking at 6rd including the srd stuff from http://bougaidenpa.org/masakazu/archives/54 (which I guess you also got wind of).
I haven't tried your patch yet but I need some clarifications. RFC 5969 has the following elements for 6rd configuration: IPv4MaskLen, 6rdPrefix, 6rdPrefixLen, 6rdBRIPv4Address. >From your example, I think the following takes care of 6rdPrefix and 6rdPrefixLen: # ifconfig stf0 inet6 2001:db8:c000:0202::/32 How can we configure the IPv4MaskLen and 6rdBRIPv4Address? I suspect IPv4MaskLen is fixed at zero (use all 32 bits) in this patch.(?) As I understand from the specs, this can be variable. It seems that at the CE, the IPv4 address of the BR is automatically calculated from the dst/src IPv6 address. But what if the embedded IPv4 address is not the whole 32 bits (IPv4MaskLen > 0)? Also, you mentioned that prefixlen of stf is from 0 to 32. Is this the same as 6rdPrefixLen? I think 6rdPrefixLen can be more than 32. Lastly, I'm a bit confused with the IPv6 default route at the CE (set to 2001:db8:c000:0201::1) since there's supposed to be no IPv6 connection between the CE and the BR, only IPv4.
